Basic Dysrhythmia-Relias Test (Latest 2025/2026 Update)
with Verified Answers | Graded A.
1. normal sinus heart rhythm originating in the sinoatrial node with a rate
rhythm in patients at rest of 60 to 100 beats per minute
2. Sinus Arrhyth- Appearance is ALMOST NORMAL:
mia Respiratory - Circulatory interaction
Rate INCREASES with INSPIRATION (IN=IN)
3. Sinus Bradycar- <60
dia normal sinus rhythm
4. Sinus Tachycar- >100 (100-150)
dia normal sinus rhythm
5. Premature Atri- Heart Rate: Depends on underlying rhythm
al Contraction Regularity: Interrupts the regularity of underlying rhythm
(PAC) P-Wave: can be flattened, notched, or unusual. May be
hidden within the T wave
PRI: measures between .12-.20 seconds and can be pro-
longed; can be different from other complexes
QRS: <.12 seconds
6. Sinus Ar- - SA node doesn't fire
rest/Pause - notice absence of P-wave for a complete cycle (a missed
cycle)
length of pause ` multiple of normal rate (block)

7. Atrial Fibrillation an irregular and often very fast heart rate originating from
(A-Fib) abnormal conduction in the atria
8. Atrial Flutter irregular beating of the atria; often described as "a-flutter
with 2 to 1 block or 3 to 1 block"
9. Junctional 40-60 Regular!
Rhythm -impulse from AV node w/ retro/antegrade transmission
- P wave often inverted/buried/follow QRS
- slow rate
- narrow QRS (not wide like ventricular)
10. Junctional Tachy- >60 bpm (ms. K; 150-250)
cardia - KEY: will be regular (consistent)
- AV junction produces a rapid sequence of QRS-T cycles
- p-wave often inverted/buried/follow QRS
11. Premature Junc- Inverted p wave or hidden p wave
tional Contrac- PRI<0.12 or none
tion Normal QRS
12. Supraventricular an abnormal heart rhythm arising from aberrant electrical
Tachycardia activity in the heart; originates at or above the AV node
(SVT)
